THRASHiNG-MACHINE SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 284,675, dated September 11, 1883,

Application filed January 22,1883. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM N. RUMELY, a citizen of the United States, residing at La Porte, in the county of La Porte and State of Indiana, have invented a new and useful Improvement in Thrashing-Machine Separators, of which the following is a specification.

My invention relates to an attachment for that class of thrashing-machine separators known as "vibrator-separators or vibrators, and in which what are known as shaking (tossing, 'lifting, or vibrating) rakes (forks or fingers) are or can be used in connection with the shaking (or vibrating) tables pans or chutes) of 4 such separators; and

Figure 1 is a view of all the parts of my improvement. Fig. 2 is a side elevation of a vibratorthrashing-machine separator, showing my improvements attached. Fig. 3 shows a plan of one of the shaking-rakes of a vibrator-separator, and Fig. 4 shows in detail the construction of the bracket and the adjustingbolt and nuts.

In the figures, 0 represents the cylinderpulley; a a, ahorizontal side piece of the frame of the separator; 00 w, an ordinary shakingpan 7 suspended by rods h h to the side piece, a a m m, the side frame-piece of the pan ac w and P represents the pitman-rod, which imparts the vibrating motionto the shaking-pan.

B represents the rake cross-bar; f, the rakefingers; o, bearings for the'lower ends of the b is an angle-iron bracket; 0, a bolt with a chamfered nut, a, and a jamnut or lock-nut, n. '2: is an eye in the bolt 0; s, a helical spring; Z, a loop of the latter; r, a loose wire loop, and p is a pin or key. The arrows indicate the direction of the oscillating motion of the-parts to which they are adjacent.

The use of shaking-rakes similar to that shown in Fig. 3 is now common, and where arms are attached at o there are various means of imparting an oscillating motion to them, or of guiding their upper ends, as the construction may require. My invention has reference to guiding, adjusting, and cushioning the upper ends of the arms 0 of such rakes, and, as the result, to adjust the inclination of the rake teeth or fingers and to cushion the whole mechanism of the rake. I accomplish the above ends by the use of the helical steel springs 88,

the adj usting-bolts c 0, nuts 12 n and a a, and the angle-iron brackets b b. 1

By reference to Figs. 1 and 2 it Wlll be seen that the upper end of lever 0 can be adjusted so as to give less inclination to the fingers f by drawing the upper end toward the right hand. This is accomplished by loosening the nuts or and a on the left of lever 0 and tightening the nuts 12. and n on the right of the lever similarly, that a greater inclination may be given the fingers f by moving the lever and the nuts in the opposite. direction. The springs as hold the lever 0 in the proper position while permitting that slight up-and-down motion of its upper end corresponding with and consequent upon the vibratory motion of the shaking-pan w m,- and they at the same time cushion the vibrations of the rake mechanism.

The details of the construction of my device are made evident from an inspection of Figs. 1 and 4. r

In Fig.4. an angle-iron bracket, b, is shown, partly in section and bolted to the under side of the side frame-piece, a a, by means of bolts or screws n". Of course the brackets may be bolted in any position and to any object so long as the bolts 0 c retain a position approximately at right angles to the length of the lever 0. The hole in the bracket b for the bolt 0 is made larger than the diameter of the bolt and is countersunlnand the nut a is chamfe-red to fit the countersink. The'object of said construction is, that when the bolt 0 is under'the pull of the spring 3 all the bearing and wear will come upon the chamfered surface of the nut n, and hence prevent abrasion of the threads of ,the bolt 0. The nut n is a jam-nut or lock-nut, used to prevent the nut n from coming loose. One end of the spring 5 has a loop, Z, which is placed around the top of the lever o, and the other is loopedinto the eye z of the bolt 0. The lever 0 may have a shoulder upon which the loops Z Z of the springs s 8 may rest, or a piece of wire, r, may be looped around the lever o to answer instead of a shoulder. A pin or key, 1), placed above the loops Z land through lever 0 prevents the springs from becoming detached. The ends of the springs s 8 could, however, be fastened to lever 0 otherwise, as by looping them through a hole or holes in the top of lever 0.- What I claim as new, and desire to secure by Letters Patent, is

The combination, with the rake-arm, of the helical spring 8, the bolt 0, provided with an eye and a chalnfered nut, as shown and described, zmd the countersunk bracket 1), as an ADOLPH MAYER.
